DOUBLE BARRELED FIREARM Filed April 10, 1929 Patented Dec. 23, 1930 STATES ljidl l g rA'ra r enrich LOUIS srInNNoN, on NEW HAVEN, CONNECTICUT, ASSIGN'OR To wINonnsrnn RE- rnarrne ARMS co, on NEW HAVEN, CO NECTICUT, A oonronn'rron or DELA- WARE DOUBLE-BARRELED FIREARM Application filed April 10, 1929. Serial No. 354,089.

This invention relates to an improvement 1n double-barreled firearms and particularly to double-barreled firearms having two triggers, the object being to provide a simple, convenient and reliable firearm of the type described in which the finger-reach, i. e. the distance between the finger-pieces of the respective triggers and the small of the stock, is substantially the same for both triggers.

A further object of my invention is to provide a firearm of the character referred to with a safety-mechanism designed to automatically prevent both triggers from being pulled into their firing positions at the same 5 time.

A still further object of my invention is to provide a double-barreled firearm having two triggers, a slight draft upon either one of which will automatically hold the other 2 trigger against being pulled into its firing position.

With the above objects in view, my invention consists in a double-barreled firearm having certain details of construction and 25 combinations and arrangements of parts as will be hereinafter described and particularly recited in the claims.

In the accompanying drawings:

Fig. 1 is a broken view in side elevation of a trigger-mechanism constructed in accordance with my invention, the trigger-mounting plate thereof being broken away and the triggers being shown in their normal pos1- tions;

Fig. 2 is a top or plan View thereof;

Fig. 3 is a vertical longitudinal sectlonal view through the trigger-plate and mounting-block and showing the right-hand trigger pulled rearward for releasing the firingmechanism of its complementary barrel and, at the same time, automatically locking the left-hand trigger against operation;

Fig. 4 is a view corresponding to Fig. 3 but showing the left-hand trigger pulled rearward in position to fire its complementary barrel and to efiect the automatic locking of the right-hand trigger against similar rearward pull; a V

Fig. 5 is a transverse sectionalvlew taken on the line 55 of Fig. 1;

Fig, 6 is a detached perspective view of the right-hand trigger; a

Fig. 7 is a corresponding view of the lefthand trigger;and

Fig. 8 is a similar but smaller-scalejview of the trigger-spacing plate.

In carrying out my invention as herein shown, I employ a trigger-mounting plate 10 which is adapted to be installed in the usual manner in a double-barreled firearmand is provided with an upstanding mountingblock 11 formed with a longitudinal slot 12 extending from front to rear therethrough and intersecting at its rear end the'forward end of a slot 13 in the said trigger mountingplate 10.

Installed in the right-hand side of the slot 12 in the mounting-block 11 above referred to is a plate-like right-hand trigger 14 extending also downward through the slot 13 in the trigger-mounting plate 10 and having a forwardly-inclined depending arm 15 terminating in a knurled forwardly-facing finger-piece 16 located closely adjacent the underface of the said trigger-mounting plate. V

Installed in the left-hand side of the slot 12 of the mounting-block 11 and extending downward through the slot 18 of the triggerplate is a plate-like left-hand trigger 17 having a relatively-long forwardly-curved depending arm 18 terminating in a knurled forwardly-facing finger-piece 19. In orderto prevent the triggers 14 and 17 a and particularly their depending arms 15 :and 18 from rubbing one upon the other, I interpose between the plate-like body-portions of the said triggers a fiat sheet-metal spacing-plate 20, as shown in Fig. 5. y

The right-hand trigger 14 is provided near its upper edge about midway of its length with a transverse bearing-passage 21 adapted to receive a transverse screw-stud 22 extending between the respective opposite sidewalls of the mounting-block 11 and upon which the said trigger 14 rocks.

The under-edge of the right-hand trigger 14 is formed with an under-cut notch 23 adapted to receive and hold in place one arm -24 of a V-shaped' sheet-metal trigger-spring 25, the complementary free arm 26 of which bears against the upper face of the triggerplate 10, as clearly shown in Figs. 3 and 4, and

. V The left-hand trigger 17 is provided near sharpedge, as, clearly shown inFig. 6 of the drawings. Near its'rear upper edge the said triggerlt is provided with a sear-lifting nose 30 adapted to engage and lift the inwardly- .turnedfingerixl of'the. right-hand sear 32 of the firearm so; as to release the firing-1nechanism of the-right-h-and barrel (not shown) controlled: thereby.

itsforward!end Fi-g.'7) with a transverse bearing epenmgfiit receiving a transverse screw-stud 34 extending between the respec-. .tive. opposite side-walls of the bearing-block 11 near thel'ower forward end thereof and providing forthe pivotal mounting of the left-hand trigger 17 aforesaid.

Formed atthe forward upper corner of the left-hand trigger 17 is a guard-nose 35 forwardly andupwardly tapered to a relatively sharp edge and adapted, as will herein'after appear, to co-actwith the guardlug 29.0fthe right-hand trigger 14. v If a The said trigger 17 is formed in its upper edge with an under-cut notch 36 receiving the lower. arm 37 of a V-sh-aped sheet-metal trigger-spring 38, the complimentary arm 39, of which bears against the upper wall 40 ofthe-slot. 12 in the mounting-block 11- before referred. to, and exerts aconstant effort to swing the left-hand trigger 17 in a clockc Wise direction so as to maintain its fingerpiece 19 in its forward or normal position. The clockwise swinging movement of the left-hand trigger 17 is limited by providing it with a stop-shoulder 41engaging the forward wall 28 of the slot 13 in the triggerp-late 1'0.

The said trigger 17 is also provided with a transverse clearance-slot 42 for the clearance of the screw-stud 22 upon which the righthand trigger 14 rocks and is also formed at its rear 11- erend with a sear-liftin nose 43 adapted to engage and lift the inwardlytur'ned finger 44 of a left-hand sear 45 controlling thefiring-mechanism (not shown) of the left-hand barrel of the firearm.

Etwill be noted from thedrawings that the finger-piece 16 of the right-hand trigger 14 'ers. e

If the user of the arm wishes to first fire lies above and slightlyforward Oftlle finger I piece 19 of the left-hand trigger 17 so that both of the said finger-pieces are located at he L substantially the same distance from small of thestock (not shown) of the firearm, c whereby the user of the "un when once accustomed to the firearnn is not compelled to have his hand assume a different position in order to reach either of the respective trigthe righthand barrel of the firearm in which i only improved trigger-mechanism as incor porated, in preference to the left-hand barrel, he will engage his trigger-finger with the finger-piece 16 ofthe right-hand trigger 14 and draw rearward thereupon with the effeet of rocking the said trigger COLllltBf-ClOClI- s wise and causing the sear-lifting nose. 30.

thereof to engage the inwardly-turned finger 31' of the right-hand sear 32 and so release the firing-mechanism of theright-hand ba r erl, which maybe of any approved type.

Coincidental with the upward movement of the sear-lifting nose 30. of the. trigger 14 as just above described, the guard-lug 29 will 'be swiing downward in front of the guardnose of the left-hand trigger 17, as'shown 111 Fig. 3, and so prevent the said left-hand trigger from being rockedcounter-clockwise to release, the firing-mechanism ofthe lefthand barrel until such time, as rearward draft upon the right-hand trigger l4fis re-' laXed and. the same isfrestored to its normal position (Fig. 1)]by its'spring25.

Conversely, should it be desired ,tofirst fire the left-hand barrel of the firearm in pref erence to the right-hand barrel thereof, the user'wlll engage his trigger-fingerwith the finger-piece 19 of the left-hand trigger 17 and 'draw the latter rearward so as to rock the left-hand trigger counter clockwise, with the effect of causing its sear-lifting nose 43 to engage and lift the inwardly-turned finger 44 of the left-hand sear 45 so asto release the firing-mechanism of the left-hand barrel of the firearm. I r

Coincidentally with the counter-clockwise movement of the left-hand trigger as just above described, the guard-nose right-hand trigger '14, as shown in Fig. 4 of the drawings, with theefiectof preventing the descent of the said lug and hence preventing the right-hand trigger, 14 from being swung counter-clockwise to, fire the righthand barrel controlled by it until such time as rearward draft upon the left-hand trig ger 17 is relaxed and the same is restored to its normalposition (Fig. 1) by the spring 38.

In the event that the user of the arm should be so careless as to spanwith his trigger-finger the fingerpieces l6 and' 19 of both of the triggers and exert simultaneous rearward draft thereupon, the guard-lug 29 of the 35 thereof I -will be moved beneath the guardlug29 ofthe right-hand trigger will be swung slightly downward and the guard-nose 33 of the lefthand trigger will be swung slightly upward so that their sharp terminals will be brought into engagement and positively prevent both of the triggers from being swung counterclockwise. However, owing to the relatively sharp-edged character of the engaging terminals of the said guard-lug 29 and guard nose 35, a slight excess movement of one trigger over that imparted to the other will disengage the sharp terminals and permit either the gnarddug 29 to descend or the guard-nose 35 to rise, but never both at the same time. If the guard-lag 29 is first to pass the co-acting guard-nose 35, the left-hand trigger 17 will be locked against clockwise movement, as shown in Fig. 3 of the drawings. If, on the other hand, the guard-nose 35 of the left.- hand trigger passes the sharpened terminal of the said gnarddng 29, the latter will be prevented from descending and hence prevent the clockwise swin ing movement of the right-hand trigger 14.

I claim:

1. A double-barreled firearm having two triggers, each controlling the firing-mechanism of one of the barrels thereof and each provided with a finger-piece; and guardmeans comprising a pair of directly co-acting guard abutments respectively carried by the said triggers in position to be inter-engaged one with the other by a relativelyslight initial manual movement of either one of the said triggers to automatically and positively restrain the other trigger against movement into its firing position.

A donble-barreled firearm having two triggers, each controlling the firing-mechanism of one of the barrels thereof and each provided with a finger-piece; and guardmeans comprising a pair of co-acting wedgeshaped guard-abutments respectively carried by the said triggers and brought into play by a relatively-slight initial manual movement of either one of the same to automatically and positively restrain the other trigger against manual movement into its firing position, the said wedge-shaped guard-abutments having their respective apices directed one toward the other.

3. A double-barreled firearm having two triggers, each controlling the firing-mechanism of one of the barrels thereof and each provided with a finger-piece; and guardmeans brought into play by a relatively-slight initial manual movement of either one of the said triggers to automatically and positively restrain the other trigger against movement into its firing position, the said guard-means comprising a guard-lug laterally offsetting from one of the said triggers and a co-acting guard-nose carried by the other of the said triggers.
